The author of this book is the former Soviet science writer Ilin, the original author of the well-known science masterpiece "One Hundred Thousand Whys".

The theme of this set of books was proposed by Gorky. He once said to Ilynn: "You know, how I want to start writing this book? Please imagine that endless space. Stars, nebulae... somewhere deep in that huge nebula is burning the sun." The planets were separated from the sun. On a small planet, matter became active and began to create itself. So people appeared..."

In this way, Ilin and his collaborator Shegar began to write this. The story: about how man appeared, how he overcame the torture of nature, and how he conquered fire and iron; how he understood and opened up the world, and how he created and enriched the field of science...

< p> What he is talking about is that two researchers revealed the status of human beings before they were "civilized" - "he" was dominated by the natural environment and suffered from the pain of crawling before growing up. In this long and unpleasant chess game, people are initially at a disadvantage. However, from the moment "he" decided to fight, he was still the same nature and suddenly became fond of humans. People finally came out on top in the cruel competition of Tianyan.

A long time ago, human beings were just monkeys living in the forest. But later, with natural disasters, danger befell them. Their ancestors died one by one, and only Some survived and evolved into ape-men, making tools and hunting large animals. By then, they had become the overlords of nature. After that, they built houses, formed tribes, built castles, fought with neighboring tribes, and used captured people as slaves. Humanity became stronger step by step... Nothing on earth can stop human progress.

The author writes very cleverly, comparing the humans and great apes long ago to prisoners of the forest, vividly recreating the nature of millions of years ago. What's even more clever is that the author takes our ancestors as the protagonists and tells them like the protagonist's story until the end of the story. When the author writes about the progress of mankind, readers will also be happy; when the author writes about mankind's disaster, readers will also be sad, as if the fate of mankind is in the hands of the author. It reflects the bitterness and suffering of ape-man evolving into human beings, and makes us feel that it is not easy for human beings to achieve today's achievements. This can also make some people cherish their current life more. Human beings have come this far step by step because they are lucky and smart. In contrast, orangutans in zoos today can only stay in zoos and forests for their entire lives. With humans, they could never evolve like their counterparts millions of years ago.
